Brighton has often been referred to as 'London by the sea', due not only to its cosmopolitan and vibrant atmosphere, but also to its many attractions including the Royal Pavilion – once home to the Prince Regent, who first visited in 1783 – the Lanes with their antiques and designer shops, and the Palace Pier. With London just 50 minutes away by rail, Brighton Marina is the largest marina in the UK and has long been a popular place to visit on the south coast.

With data on more than 600 Superyacht marinas, the Dockwalk team is pleased to present its online Superports directory.

Previously only available in print, the Superports directory contains information including contact details, facilities at the berth and local services. It also provides vital logistical information such as lat/long co-ordinates, berth numbers and sizes, prices and distances to local airports.

What's more, the whole thing works with Google mapping. Select a region or enter a location, rollover an anchor and see the name, location and photo of the marina. Click on it to load all the info on your chosen marina.

When you've chosen a marina, you'll notice a list of local services classifications in the right hand column. Right now it's fairly empty. That's where you come in.

We're building the site around our users, and we want to publish the things that are most useful to you. As you travel around the world, you can recommend the best bars, friendliest agents, most efficient electricians and the quickest taxis - to name but a few. And as the directory builds up, you can look up services that have been recommended by other Captains and Crew.

So if you've had a great night out, found the best surf shop or been impressed with an emergency repair, click on the Recommend A Local Service link and share it with crew around the world.
